Specifying the computation method for blank value and daily factor
Defining the blank value calculation method
Proceed as follows:
 Open the "Configure Calculations" dialog in the operating software by selecting Options >
Settings > Calculation.
 In section "Blank value determination" define the calculation method:
If you...
 ... select "sequentially" a separate blank value is computed for every element in every group
of blank value samples; this value is entered in the respective blank value column until the
next group of blank value samples.
 ... select "entirely" all blank value samples in the series are used to compute the blank
value. This blank value is then applied to all samples in the series.
 ... select "manual input" blank value calculation is not performed - even if there are blank
samples in the series. This allows manual input of blank values for individual samples.
 ... "autom. activate "automatic blank value calculation" the blank value is automatically
computed at the end of every analysis. This option ist not available if manual input has
been checked.
 Then click OK to save your settings.
Defining the daily factor calculation method
Proceed as follows:
 Open the "Configure Calculations" dialog in the operating software by selecting Options >
Settings > Calculation.
 In section "Factor determination" define the calculation method:
If you...
 ... select "sequentially" then the daily factor is computed group-by-group and changes
throughout the day.
 ... select "entirely" the daily factor is computed on the basis of all factor samples in the file.
An average factor is computed.
 ... select "manual input" factor calculation is not performed - even if there are factor samples
in the series. This allows manual input of daily factors for individual samples.
 ... "autom. activate "automatic factor calculation" the factor is automatically computed at the
end of every analysis. This option ist not available if manual input has been checked.
 ... activate "upper/lower calib. range distinction" both for the upper and lower calibration
range separate factors will be calculated. This requires separate factor samples for each
range.
 Then click OK to save your settings.
Enabling/disabling acoustic signals
Enabling/disabling acoustic signals
Proceed as follows:
 Open the "Acoustic signals" dialog by selecting Options > Settings > Acoustic Signals.
 Decide:
If you want to...
 ... switch on a signal, check the appropriate checkbox.
